Description

Lateral prestress escape device

[0001] The present invention relates to the field of public security fire rescue technology, and in particular to a method for manufacturing a building fire escape device.

Background technique

[0002] Various building fire escape devices are currently known to employ a speed reduction mechanism to reduce the speed at which the escaper descends, allowing the escaper to escape at a safe speed. The known speed reducer of the escape device is various, and the generator and the hydraulic system with complicated structure are used as loads to achieve the purpose of deceleration, and more frictional force is used as the load, and the volume is large and small, and the structure is complicated. There are also relatively simple, and the operation methods are also varied. There are certain limitations in use, and the ropes carrying the escapers and the protruding edges of the windowsill or the building will rub against each other, so that the window sill and the outer edge of the building will be roped. The unsafe factors caused by damage, especially the long distances of high-rise buildings, are more serious. The danger of unsafe factors is more prominent. At present, high-rise building fire rescue is a very difficult problem, so there is an urgent need for a structural unit. Use a flexible, easy-to-operate escape.

Summary of the invention

[0003] The idea of the present invention is: at one end of a rope, in the longitudinal direction (the length of the rope) is divided into A end and B end, if the A end is fixed, and an external force pulls the B end, when the external force is greater than When the rope is transverse (perpendicular to the length of the rope), the rope is divided into two, and the length is doubled. The lateral stiffness of the strap is always offset by a portion of the external force throughout the process. If the lateral stiffness of the strap is replaced by an appropriate amount of lateral prestress (or the stiffness is controlled to an appropriate size), use this appropriate amount of lateral prestress ( Horizontal firmness) to offset the escaper Part of the weight of gravity, the rope has an escape function for escapers to use to escape.

[0004] The technical solution disclosed by the present invention is characterized in that: a certain method is used to generate or use a certain method to jointly produce an appropriate size of lateral prestress or lateral firmness (horizontal refers to the tape (tape, The rope) is longitudinally oriented and stored in the interior of the tape (cord, rope) or between the tape (cord, rope) and the tape (cord, rope) to counteract the escape Part of the weight of the person's weight allows the escaper to escape at a safe rate.

[0005] Another feature of the technical solution disclosed by the present invention is: the escape distance (falling height) of the transverse prestress escape device can reach twice the length of the escape strap (rope, rope), and can also be used with the escape device. The length of the tape (cord, rope) is equal.

As described above, a tape (cord, rope) having an appropriately sized lateral prestress (lateral firmness) constitutes a transverse prestress escape.

[0007] As described above, the transverse prestressing (transverse firmness) of an appropriate size of the transverse prestress escape can be produced by either a method or a combination of several methods.

[0008] As described above, the lateral prestressing force (lateral firmness) of the appropriate size of the transverse prestress escape can be stored inside the tape (cord, rope) or in the tape (cord) , rope) between the tape (cord, rope) or between the tape (cord) and the rope.

[0009] As described above, the lateral prestressing escape device has an appropriate size of lateral prestress (lateral firmness), and the magnitude of the value may be the same in different lengths of the tape (cord, rope). Can be different.

[0010] As described above, a tape (cord, rope) having a laterally prestressed size of an appropriate size is not limited to a certain form, and may be stretched or gathered together, in a manner of gathering. It can also be any way of reciprocating lamination, coiling, winding or the like. [0011] As described above, a transverse prestress escape device composed of a tape (cord, rope) having an appropriate size of lateral prestress (lateral fastness) may be composed of a tape (cord, rope). It can also consist of several strips (tapes, ropes) or several strips (tapes) and several ropes.

[0012] As described above, a transverse prestressing escape device composed of a transversely prestressed tape (cord, rope) of an appropriate size, wherein the materials of the respective tapes (cord, rope) may be the same Can be different.

[0013] As described above, a transverse prestressing escape device comprising a transversely prestressed tape (cord, rope) of an appropriate size, wherein the cross-sectional shape of each of the tapes (tapes, ropes) may be Arbitrary.

[0014] As described above, a lateral prestressed escape device having a suitably pre-stressed tape (cord, rope), wherein the cross-sectional area of each of the tapes (tapes, ropes) may be The same can also be different. The cross-sectional area of each of the tapes (tapes, ropes) may be the same or different in different lengths of the tape (tapes, ropes).

[0015] An advantage of the present invention is that: the method disclosed in the present invention smashes the inevitable deceleration mechanism of the currently known escape device, and the transverse prestress escape device manufactured according to the method disclosed by the present invention is used in the tape. (rope, rope) will not cause displacement friction with the window sill of the building and the protruding outer sill, causing damage to the tape (cord, rope). The structure is simple and easy to operate. The escape can be flexible depending on the scene of the fire. Choose a window suitable for escape, balcony escape, because the structural can only use a long enough tape (cord, rope) without its large size, so it is especially suitable for the escape of high-rise building fires. The invention can also provide a "convenient passage" for the firefighters to rescue the trapped person, and can avoid the danger that the firefighter faces when the trapped person walks through the fire. According to different situations Lateral prestressed escapes can be used with some corresponding brackets. If the escape strap is kept at a suitable distance from the wall, the escaper can escape more smoothly.

detailed description

[0016] Embodiment 1: The production scheme of the escape device is a carbon fiber rope or a glass fiber rope which can be used with high strength, light weight, high temperature resistance and corrosion resistance. Leave one end (end) of the strap with the appropriate length to connect with the seat belt of the escaper's waist; after applying adhesive on both sides of the strap, rewind the strap back and forth, at the beginning of the stacking The length of the belt is the largest, and each layer is laminated one by one, and the length of the rope is appropriately reduced, so that the rope which is laminated on one piece finally forms a trapezoid or a triangle, when the adhesive strength and the rope When the width of the belt is properly matched, a lateral prestress of an appropriate size can be produced. When the rope is released by gravity, it will be released from the uppermost layer layer by layer. At the other end (head end) of the rope, there is a collar or a buckle for hanging at the building to be secure or connected.
